Abstract

A bidirectional transmission circuit for inputting/outputting a signal from/onto a bidirectional transmission line includes: a transceiver for transmitting/receiving a signal; a first element having an impedance; a second element being a short line; and a switching unit for coupling the transceiver to the bidirectional transmission line via the first element when the transceiver transmits a signal, and coupling the transceiver to the bidirectional transmission line via the second element when the transceiver receives a signal.
